Classic ASP is a similar framework to PHP. In Classic ASP there are a Session and a Application object. The Session object can store variables that will be available during the user session (using session cookie). And the Application object can store variables that will be available to all other scripts. So when the server starts, you put everything in the Application object, so when you get a new request, you load the data from the Application object instead of re-creating everything, doing database lookups etc on every request. This makes Classic ASP very performant with sub-millisecond requests. I used Classic ASP until recently and have now switched to Node.JS which uses an event loop. Per-request as in ASP and PHP is much easier then a event loop. In Node.JS for example, it's very common to pull in a framework like Express to do the routing, while PHP and ASP already do that job for you. One problem with ASP and PHP however - they're not optimal for real time stuff like chats or progress-bars.
